[0027] Specifically, the driving platform 51 is rotationally connected to the tool shaft seat 5, so that the driving platform 51 can rotate independently of the vertical rail 4. The rotation of the driving platform 51 drives the extension platform 52 and the driving shaft 53 to rotate synchronously, thereby driving the tool 55 to rotate.

[0028] A driving shaft 53 is provided at both ends of the tool 55 , and a tool shaft 54 ​​is provided at the connection between the tool 55 and the driving shaft 53 .

[0032] A bearing seat 23 is provided at the bottom of the center line of the stop platform 22. One end of the bearing seat 23 is flush with the outer end of the stop platform 22, and the other end of the bearing seat 23 exceeds the other end of the stop platform 22.

The slide 12 and the slider 14 control the horizontal feed of the tool 55 and the workpiece. The movement between the lifting seat 1 and the first slide 11 and the rotation of 16 are coordinated to enable the tool 55 to process different angles of the workpiece, thereby achieving precise processing of gear discs of different sizes.
